CARD-FORMING MACHINE.

Application filed March 31, 1924. Serial No. 703,046.

machine for forming cards'from a contin-' uous web, being especiallyadapted to form cards having grouped samples of thread mounted thereon.It further has for its object to produce a machine in which the web willproperlyrregister with the cutting mechvention, reference being ,had tothe accomof the same drumactmg supply, beinga section on the line 6-6,'

anism so that the severing will take place at definite points betweenproperly spaced rows of adhesive, securing the threads thereto. Itfurther has for its object to produce a machine which when forming thecards will trim'ofi' the edges of the web. It further has for its objectto produce a machine which, by simple changes, may be adjusted "forcutting cards of various widths. I

The following vis a description of my inpanying drawings, in which,

Fig. 8 is an enlarged plan view of the finished cards; and

Fig. 9 is an enlarged edge view of thefinished product. Y

Referrlng more particularly to the drawwhich it is desired to cut ings,2 is a web of paper such as cardboard, by knives located at the otherend of the machine. This Web is mounted upon a drum 4 carried by asuitably mounted shaft 6 and has equally spaced perforations along itsedges.

Adjacent the drum 4 is a take-off device comprising a drum 8 mounted insuitable bearings and driven by gears 10 and 12, the latter being drivenby a sprocket chain 14 engaging a sprocket 16 and a sprocket 18, thelatter being mounted upon the main shaft '20 of the machine. This mainshaft 20 is provided with a large gear 22 and is driven by a small gear24 mounted on the same shaft with the. driving pulley 26 to which poweris primarily applied.

The drum 8 is a registered drum, being provided with spaced projections28 which engage spaced perforations 30 shown in Fig. 7 in the edges ofthe web to be out. The pulley 26 acts through the intermediateconnections to continuously drive the drum 8 so as to. take off the webfrom the drum 4 at a uniform rate. The drum'8 is provided,

with pressure rolls 32 which serve to hold' in place thereon and inengagepivotally connected to the ends of the bar- 36. These knifeoperating eccentrics being mounted upon the main shaft 20 arecontinuously operated so as to produce a periodic rise and fall of theknife which in its downward position engages a severingedge upon theadjustable plate 44.-

In order to intermittently feed the web to the knife 34 in timedrelation so that the web will be severed at theproper points, I providea feed controlling roll 46, the same bein a registered drum havingprojections 48 w ich are adapted to engage the perforations in the edgesof the web. The web passes from the roll 8 to the drum 46, pressurerolls 49 being provided for holdin the-web in contact with the drum 46and of the machine is prov particularly with the projections 48. The Webas it passes from the roll 8 to the drum 46 is permitted to hang down sothat there is considerable slack in it, this being necessary for thereason that the motion of the drum 46 is an intermittent motion, whilethe motion of the drum 8 is a continuous motion. These two drums are,however, so connected that the amount of paper which passes over eitherof them during a complete revolution of the shaft 20 is the same.

In order to periodically actuate the drum 46 and also the slitting andfrictionally driven pulling devices later described, I provide aneccentric 72 mounted on the main shaft 20, which through the link 70connected to lever 50, mounted on shaft 52, and provided with a pawl 54,actuates the ratchet wheel 56, the ratchet wheel 56 in turn beingconnected to and actuating gear 58. The gear 58 engages gear 60 locatedon the shaft of the drum 46 and so actuates this drum. The shaft of thedrum 46 carries an index wheel 62 which is engaged by a roll pawl 64carried on an arm 66 and held by a spring 68 in yielding contactwith theindexing device. The rate between the gears 58 and 60 being in the ratioof two to one, the indexing cavities of the indexing device 62 aredouble in number the teeth upon the ratchet wheel 56.

vThe gear 58 also drives the gear 80 which is on the roll 74 of aslitting device shown in Fig. 4. The slitting device comprises a roll 74having grooves provided with cutting edges, which roll is geared to asplined shaft 78 on which is adjustably mounted rotary knives 76.

Adjacent to the slitting device and between the same and the knife is africtionally driven pulling device which acts to keep the web taut afterit leaves the registered drum 46 and feeds it to the knife as fast asthe drum 46 will permit. The gear 80 on the roll of the slitting devicebefore described, drives the gear 92 which is compounded to gear 90 andmounted with it on a stud, the gear 90 in' turn driving a frictionslip'gear 88.

The friction slip gear 88, as shown in Flg. 5, drives a lower roll 82which is geared to an upper roll 84 at 86. On account of theseconnections the gear 88 is driven at a rate which tends to move thesurface of the rolls 82 and 84 somewhat faster than synchronously withthe surface of the drum 46,

carrying the registering projections 48. The friction slip connection,however, shown in Fig. 5, yields so as to permit movement between thegear 88 and the rolls which it drives so that the effect is simply tomaintain the web under tension after it leaves the drum 46 and to feedit forward when the drum 46 permits, the web acting to slow the feedingrolls down below the rate at which they tend to rotate. The action ofthe drum 46, and rolls 82 and 84, is so timed that they feed the paperafter the knife 34 has gotten out of the way and complete their feedingaction before it has descended-to cutting position. When the knife 34descends so as to sever the web, it cuts the central portion and alsothe slitted side portions, the central portions being delivered to asuitable receiver 94 by a support 96 while the side portions 98 shown inFig. 8 fall on either side of the support 96.

The indexing wheel 62 is for the purpose of keeping the drum 46 fromoverrunning and also to maintain it fixed against the friction pull ofthe gear 88, the spring 68 being strong enough to cause the rollerrpawlto prevent the pulling action upon the web from revolving the drum 46.

The rate of feeding of the web to the knives can be changed by removingthe ratchet wheel 56, shown in Fig. 2 the indexing disk 62 and thepinion 12 and substituting therefor other similar devices having thenecessary ratios for the desired results.

The upper roll 84 shown in Fig. 5 of the pulling device is preferablymade with an elastic covering such as rubber so that it may yield to thedifferent thicknesses of thread upon the web and also have an increasedfrictional bearing thereon without undue pressure.

This roll .84 is provided with adjusting means so that itspositionrelative to the roll' 82 can be adjusted.

Figs. 7, 8 and 9 show enlarged views of the end of the web and of thecomplete prodnot, the scale being nearly full size. This web is composedof a pasteboard base 2 on which are mounted groups of threads 100,

the groups being parallel to the axis of the web and the threads thereonbeing parallel to one another. The threads are separately held to theweb by transverse lines of adhesive 102, preferably four in number, thisbeing the product of a machine forming the subject matter of aco-pending application Serial No. 703,047, filed March 31, 1924. The endof the sheet as it passes beneath the slltting knives '7 6 is slit asindicated at 104, which slitting takes place on a line within theperforations 30. When the end of the strip is severed by the knife 34,the product shown inFig. 8 is produced, the severing action, on accountof the. timing of the machine, taking place at the centers of the groupsof lines of adhesive 102 so that a plurality of separate cards 106 isproduced,

each having a plurality of groups of sample threads secured thereto by apear of lines of adhesive situated adjacent to each of their ends andready to be mounted in any desired manner for display purposes.
